Bently Nevada 330703-000-060-50-12-00 3300 XL 11 mm Proximity Probe

Description

An unarmored, metric threaded M14 x 1.5 steel probe body (base model 330703) featuring 0 mm unthreaded length (Option 000), a 60 mm overall case length (Option 060), and a 5.0 meter total system length (Option 50) defines the 330703-000-060-50-12-00 3300 XL 11 mm Proximity Probe.

This configuration incorporates Option 12, equipping the transducer with a FluidLoc cable and a miniature coaxial ClickLoc connector without a connector protector. Unlike standard triaxial cables, FluidLoc technology prevents leakage of oil or other process fluids through the cable interior. With no armor sleeve and Option 00 signifying no hazardous area agency approvals are required, this specific 5.0-meter probe is engineered for direct integration with 5.0-meter 3300 XL Proximitor Sensors (such as model 330780) in critical machinery monitoring setups.

Features

• Option 330703 base design features an M14 x 1.5 metric thread without armor for standard installation.
• Option 000 specifies a 0 mm unthreaded length, allowing the case to be fully threaded for maximum mounting flexibility.
• Option 060 provides an overall case length of 60 mm.
• Option 50 provides a 5.0-meter (16.4 feet) total cable length, matching 5.0-meter Proximitor Sensor systems.
• Option 12 utilizes a FluidLoc coaxial cable to block fluid transmission through the inside of the cable sheath.
• Miniature coaxial ClickLoc connector provides a secure, low-loss electrical connection without a connector protector.
• Polyphenylene sulfide (PPS) probe tip material withstands harsh industrial environments.
• Operating temperature range of -52 degC to +177 degC (-62 degF to +351 degF) handles extreme process temperatures.

Applications

• Axial (thrust) position measurements on steam turbines.
• Ramp differential expansion measurements on steam turbines.
• Rod position or rod drop measurements on reciprocating compressors.
• Shaft vibration and rotor position monitoring of fluid film bearing machines.
• Tachometer, zero speed, and Keyphasor phase reference signal generation.

Installation Guidelines

• Maximum Case Torque: For M14 x 1.5 probe cases, do not exceed the maximum rated torque of 63.3 N-m (560 in-lb). The recommended installation torque is 21.1 N-m (187 in-lb).
• Thread Engagement Limit: The maximum length of thread engagement for M14 x 1.5 probes is 21 mm. Exceeding this limit may cause binding during installation.
• Minimum Bend Radius: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the entire run of the FluidLoc probe cable.
• Connector Protection: Maintain clean and dry coaxial ClickLoc connections. A finger-tight connection is recommended, up to a maximum torque of 0.565 N-m (5 in-lb). Do not use silicone tape if the connection is exposed to turbine oil.
• Target Gap Alignment: Calibrate the probe to a recommended gap of 2.5 mm (100 mils) from the target to optimize measurement range centering.
